Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

To further reduce particulate emissions, the amendm ent requires additional control measures, such as: threesided barrier with a roof and wind fence, tarps, an d barriers/wind fences for clinker piles.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when imp lemented, will result in quantifiable changes in em issions. Attach reference(s) for emission

factor(s) and other information. Attach calculatio n sheet showing how the emission information provid ed below was determined

.

Net Effect on Emissions: Increase* Decrease** N/A

Emission Reduction Commitment in SIP for this Sourc e Category: Rule 1156 and Rule 1157 (Aggregates) w ere adopted to implement Control Measure BCM-08 of the 2003 AQMP. That control measure called for a 0.7 tons per

day (tpd) PM10 reduction by December 31, 2010 off o f a 1.7 tpd emissions baseline inventory. The Rule 1156 portion

of BCM-08 baseline inventory was 0.4 tpd PM10 with an emission reduction contribution of 0.2 tpd. Thi s is what was

reported for SIP purposes, which was approved by th e EPA in March 2008.

However, during the Rule 1156 development process, the inventory baseline and reductions were updated. The

revised emissions inventory of 2.1 tpd PM10 (4.2 tp d total PM) in 2003 was reduced through rule implem entation by

1.1 tpd PM10 (2.2 tpd of total PM). This informati on was used to update the emission inventories for this source

category in the 2007 AQMP. (Note: the 2007 AQMP d oes not contain any additional emission reduction c ommitments

for this source category).

These amendments to Rule 1156 will achieve emission reductions of 0.04 tpd PM10 (0.006 tpd PM2.5, 0.09 tpd total

PM) and are in addition to the revised reductions n ow reflected in the 2007 AQMP.

Baseline Inventory in the SIP for the Control Measu re: The 2007 AQMP emission inventories contain the aforementionned

revised emissions inventory data.

Emissions Reduction Commitment in the SIP for the C ontrol Measure: The 2007 AQMP contains no addition al emission

reduction commitment for this source category.

Revised Baseline Inventory (if any): Not applicabl e.

Revised Emission Reduction Estimate (if developed): The estimated additional emission reductions for the Rule 1156

amendment are 0.006 tpd PM2.5, 0.04 tpd of PM10 and 0.09 tpd of total PM.

Note that the district’s input to the Rule Evaluati on Form will not be used as input to the ARB’s emis sion forecasting and

planning.

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY) Source s Affected by this Amendment: N/A

Percent in Nonattainment Area: N/A %

Number of Large (> 100 TPY) Sources Controlled: 2 Percent in Nonattainment Area: 100 %

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as

necessary) : 1) TXI Riverside Cement (TXI) near the city of Riv erside in Northeastern Riverside County; and 2) Ca lifornia

Portland Cement Company (CPCC) near the city of Col ton in Southwestern San Bernadino County.

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Cont inuous? Yes No

If Yes, Those Limits are in Section(s) of the Rule.

Other Methods in the Rule for Achieving Emission Re ductions are: The amendments focus on clinker mate rial handling

and storage by requiring: three-sided barrier with a roof and wind fence, tarps, and barriers/windfenc es to further reduce

particulate emissions. The amendment also includes other requirements listed in Section V below to en sure public health

protection. Since these requirements do not genera te quantifiable emission reductions, the following sections are not

submitted for SIP approval: (d)(10), (d)(11), (d)(1 2), (d)(13), (f)(2)(F), (f)(2)(G), and (f)(3).

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): (d)(11)(A) , (d)(11 )(B), (d)(12), and (d)(13)(B); however, they are no t part of the SIP

submittal. Work Practice Standards in Section(s): (d)(11) (A) , (d)(11)(B), (d)(12)(A), and (d)(13).

Recordkeeping Requirements in Section(s): (f)(2)(F ) and (f)(2)(G) Reporting Requirements in Section(s): (f)(3)CALIFORNIA AIR RESOURCES BOARD

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The amendment would reduce an addition al 0.006 tpd PM2.5, 0.04 tpd of PM10 and 0.09 tpd o f total PM from

this source category, and contribute towards attain ment of the 24-hour PM 2.5 and PM10 standards.
